Talk:Central massive object

NSCs
Aren't star clusters said to have black holes themselves? And what is in the center of irregular glaxies? 212.186.0.174 (talk) 16:29, 4 July 2019 (UTC)

Center of manybody systems -isn't it the empty barycenter?
The hypothesis that there are "central massive objects" at the centers of galaxies is falsified by experience. It conflicts with the mechanical experience that at the center of manybody rotating systems there is the "barycenter", as the orbiting bodies' common center of gravity, which is only an empty geometrical point in space. It is mechanically impossible that a massive object stay at that center, because all objects needs move about their common center of gravity.
